1. Introduction 1.1 This paper is one of a series of evidence papers produced in support of the Waste Core

Strategy (WCS). The purpose of the paper is to explore the potential for Energy from Waste

(EfW) powered Combined Heat and Power (CHP) at each of the 13 sites identified in the

Waste Core Strategy Site Options consultation (October 2009). Therefore it will provide

background as to the CHP potential for any sites that are taken forward in the process for

inclusion in the WCS or any future DPD.

2. What is Energy from Waste (EfW)?

2.1 One of the Government’s key objectives in The Waste Strategy for England (2007) is to

maximise environmental benefit from investment in waste infrastructure “through increased

recycling of resources and recovery of energy from residual waste using a mix of

technologies”. The Waste Strategy for England encourages the implementation of the

Waste Hierarchy (see the diagram below). EfW falls into the 'other recovery' category

helping to move waste up the waste hierarchy away from disposal (landfill).

Figure 1: The Waste Hierarchy

2.2 EfW includes a number of established and emerging technologies which can be defined as

both thermal and energy generating technologies. Generally, thermal combustion is the

primary technology. Many types of wastes are combustible (e.g. municipal solid waste

(MSW)), with relatively high calorific values. The energy released during the combustion of

waste cane be recovered for both heat and electricity.

5

2.3 Annex E of the The Waste Strategy for England (2007) lists various EfW technologies,

these are:

Direct Combustion (Incineration);

Advanced Thermal Treatment (ATT) - Gasification & Pyrolysis and;

Anaerobic Digestion (AD)

2.4 The government states that a technology is more beneficial if both heat and electricity can

be recovered from the waste recovery process.

Direct Combustion (Incineration)

2.5 Incineration involves the combustion of waste being burnt at temperatures over 850°C. On

arrival at the facility the waste (generally MSW and Commercial and Industrial waste (C&I))

is mixed and sometimes shredded to a more homogenous fuel that will combust. It is then

moved to a combustion chamber where oxygen is added. Combusting the waste turns

most of it into carbon dioxide, other gases and water. The process releases energy which,

through use of a boiler system, can be harnessed and turned into electricity and heat

energy.

2.6 Any material that won't burn (glass, metal, stones) collects at the bottom of the combustion

chamber and is known as bottom ash. Incinerators also create gases which are generally

acidic and contain particles. Prior to being released into the atmosphere the gases are

cleaned carefully to neutralise the acidity and remove the particles. The particles collected

along with the excess cleaning chemicals are known as fly-ash (Air Pollution Control

Residues (APC Residues)), which are classed as hazardous waste.

2.7 Modern incinerators generate and capture heat and electricity which may be used on or off-

site thereby contributing to renewable energy targets1. In some instances, incineration may

be used in conjunction with other waste management technologies as part of an integrated

facility. For example, using a pre-treatment technology such as mechanical treatment to

extract metal, glass or plastics from the waste before it is combusted or using a Mechanical

Biological Treatment (MBT) facility to produce a fuel (Refuse Derived Fuel (RDF) or Solid

Recovered Fuel (SRF)) to be used in an incinerator of other ATT process

1 The degree to which ‘renewable energy’ is generated will depend to a large extent on the nature of the waste being incinerated.

Advanced Thermal Treatment (ATT) - Gasification & Pyrolysis

2.8 ATT is a general term used for two different technologies, pyrolysis and gasification, which

can be used as part of a solution separately or together. The main difference between

ATT and incineration is the amount of oxygen used and the temperature in the combustion

chamber.

2.9 Gasification is a similar process to pyrolysis, but with some oxygen (although not as much

as incineration). This means the waste is partially combusted at temperatures above

650°C. The main product from the process is syngas, but ash is also produced. The

syngas can then be combusted to generate electricity and heat.

2.10 Pyrolysis involves breaking down the waste at 300-850°C without oxygen. It almost ‘melts’

the waste, breaking most of it down into gases and the remainder produces a solid char.

The solid char can be used like coal and the synthetic gas (called syngas, which is a

mixture of gases) has the potential to be used as a liquid fuel or to generate electricity and

heat.

Anaerobic Digestion (AD)

2.11 AD is the biological degradation of treated source segregated wastes in the absence of

oxygen. It essentially replicates the biological processes which occur in a landfill, but

under controlled conditions. The process generates a number of usable products

including:

Digestate - a fibrous product, the quality of which is determined by the feedstock.

It has a variety of horticultural or agricultural uses as it can be used as a fertiliser;

However this is not a product which can currently be produced by residual waste.

Liquor - can be used either to moisten feedstock or as a liquid fertiliser; However

this is not a product which can currently be produced by residual waste.

Biogas - rich in methane which can be used as a natural gas substitute, converted

into fuel for use in vehicles or burned to generate electricity in a CHP scheme.

3. What is Combined Heat and Power (CHP)?

Introduction

3.1 Putting it simply CHP (or cogeneration as it is sometimes known) is the simultaneous

generation of heat and power in a single process by the generation of steam/gas produced

by burning a fuel. It makes use of the heat that would normally be wasted in an electricity

generation process. It can be powered by a variety of different fuels including MSW. It is

a highly efficient process which can make a significant contribution towards reducing

carbon emissions.

3.2 CHP does not only have to be a provider of heat, it also has the potential to be used for

cooling. This option is only likely to be viable however when there is a high and constant

refrigeration demand.

3.3 In 2006 CHP plants (using a variety of fuels) in the UK produced some 28TWh2 of

electricity and 54 TWh of heat. For electricity this equates to approximately 6% of the UK’s

electricity supplies (Institute of Engineering and Technology 2008). In terms of heat,

district heating networks (see below) currently provide 4% of the UK’s heat supply,

supplying approximately 600,000 dwellings (CHPA. 2010).

3.4 CHP is most effective when there is a constant demand for electricity, heating and/or

cooling throughout the day. The ideal scenario therefore is where there is a mix of

different users, for example residential, offices, industry and municipal buildings providing

constant demand.

European Policy

3.5 At the European level there is the CHP Directive (2004/8/EC). The European Union

encourages the use of CHP because it saves energy, avoids network losses, secures

energy supply and reduced carbon and greenhouse gas emissions. The directive should

have been transposed into Member State law by February 2006. This has not fully

happened in the UK but sections of the directive have been included within existing laws.

National Policy

3.6 In March 2010, draft Planning Policy Statement 'Planning for a Low Carbon Future in a

Changing Climate' (a supplement to PPS1 – Delivering Sustainable Development) was

published for consultation and stated that:

„Local planning authorities should assess their area for opportunities for decentralised

energy. The assessment should focus on opportunities at a scale which could supply

more than individual buildings and include up-to-date mapping of heat demand and

possible sources of supply. Local planning authorities should in particular look for

opportunities to secure:

i. decentralised energy to meet the needs of new development;

ii. greater integration of waste management with the provision of decentralised

energy;

iii. co-location of potential heat suppliers and users; and,

iv. district heating networks based on renewable energy from waste, surplus heat and

biomass, or which could be economically converted to such sources in the future. „

CHP technologies and fuels

3.7 There are five main technologies that can be used for CHP. These are:

Gas Engines – Most often use natural gas to generate heat and electricity. The

engine is similar to that used in a motor vehicle which generates electricity and then

the heat is recovered.

Gas Turbines – This is the most common way of generating CHP. The turbine

produces an exhaust gas which generates steam.

Steam Turbines – This is the oldest form of CHP generation and can use any type

of fuel. The fuel is burned and the resulting steam generates electricity and heat.

Combined Cycle Gas Turbines - This is a gas turbine which generates steam at a

variety of pressures which then produces the electricity and heat.

Absorption Chilling - This technology is used when there is a cooling demand. It

uses the heat generated to produce chilled water. This process is very similar to

that taking place in a fridge.

9

3.8 There are a significant range of fuels that can be used for CHP, these include:

Natural gas

Landfill and sewage gas e.g. methane

Fuel and gas oils

Coal, ignite and coke

Biomass and biogas e.g. wood.

Solid waste, e.g. refuse, tyres

Waste gases, e.g. refinery of gas

Waste process heat e.g. steam and gases

MBT produced RDF and SRF

District Heating

3.9 District/community heating schemes allow for a number of buildings to be heated by the

heat produced in the CHP process. The heat is transferred to the consumer (homes and

businesses) in the form of steam, hot water or chilled liquid through a network of

underground insulated pipes. District heating systems are common in Scandinavia, the

Netherlands and Germany. There are far fewer schemes in the UK with only a handful of

developments incorporating such networks, e.g. Southampton, Sheffield, Nottingham,

Lerwick and the City of London.

3.10 Retro-fitting district heating networks within existing developments is possible but this

increases the economic cost of the schemes. This is because the existing infrastructure

(roads etc.) has to be disrupted to lay the heating pipes. Therefore it is much easier to

include a network within a new development before the main infrastructure is put into place.

Examples of District Heating Systems

3.11 Both schemes below developed district heating networks over twenty years ago. Since

then these networks have increased in size and are successful examples of using waste to

generate heat and power in the UK.

10

Advantages/benefits of CHP

It can be 80-90% efficient unlike power stations which only have an efficiency of

35%. The increase in efficiency results in a decrease in the CO2 emissions as the

waste heat is being used.

It has the potential to increase energy supply security and reduce dependence on

imported fuel.

It provides an economic saving of between 30-40% over electricity purchased from

the National Grid.

Good quality CHP3 which has been assessed by the CHPQA (CHP Quality

Assurance) and meets a certain criteria can receive 1 Renewable Obligation

Certificate (ROC) 4 per MWh5.

3 Good quality CHP is when it has been assessed for its energy efficiency and environmental performance.

4 ROC is a green certificate issued to an accredited generator for eligible renewable electricity generated within the United Kingdom and

supplied to customers within the United Kingdom by a licensed electricity supplier. 5 Megawatt hour – a measure of energy consumption

1. Sheffield (Veoila Environmental Services) – The network now supplies 140

buildings including public buildings, businesses and dwellings. The underground

pipes cover 44km. The heat is now supplied by an Energy Recovery Facility

which processes 225 000 tonnes of waste producing 60Mw of thermal energy

and 19mw of electrical energy. It is estimated that it saves 21 000 tonnes of

CO2 emissions compared to conventional energy production.

2. Nottingham (Enviroenergy) – The scheme in Nottingham provides energy to

5,000 homes along with public buildings, schools and Nottingham Trent

University. The energy is produced as a result an incinerator which burns

145,000 tonnes of waste. The steam produced as part of the incineration

process is exported to an energy centre nearby where it gets turned in to heat

and electricity. The heat is then transported using underground pipes to the

users and the electricity is fed in to the National Grid.

11

Limitations of CHP

The insulated pipe work required to transport heat is very expensive which often

means the identification of potential sites for CHP scheme are within a limited radius

as it is not cost effective after a certain distance.

CHP schemes need to be relatively close to heat users, due to the cost of

implementing a network and the associated heat loss through the length of the

network (1 c per km);

Retro-fitting is considerably more expensive than new development due to existing

infrastructure already being in place;

There are often issues over the funding of a CHP scheme/district heating network.

There need to be a 24 hour heat demand and this has to be large enough to make

the scheme pay for itself.

There are often problems with connecting to the National Grid which can increase

the cost.

When both heat and electricity are generated the amount electricity produced

decreases compared to when only electricity is created.

4. Assessing the CHP potential of the 13 site options

4.1 This section of the paper contains a basic assessment of the CHP potential of the 13 sites

identified in the Waste Core Strategy Site Options Consultation (October 2009).

4.2 Each site has been considered in turn for ease of reference. For each site the following

general information is provided in a series of site schedules attached below:

Site name

Site area

Site Plan

Existing use/designation

Ownership

Existing heat users within 1km

Potential heat users within 2km

4.3 Assuming that any electricity generated at each site will be exported to the National Grid,

this paper seeks to identify if there is any scope to use the heat from the process. In

particular whether there are any existing or potential heat users on or within ‘close

proximity’ of the site. This includes industrial/employment uses, other commercial uses,

residential, public buildings, hotels/catering, retail, education and health facilities.

4.4 Ideal heat users include those with a continuous demand for heat such as certain industrial

processes, hospitals etc. Those with variable, possibly seasonal heat demand, such as

residential development are less ideal although can still be catered for e.g. through district

heating particularly where they form part of a mixed-use development for example housing,

offices and leisure facilities where there is variable heat demand throughout the day.

4.5 It is understood that modern technology means the heat from an ‘energy from waste’ facility

can be transferred up to 15km from where it is generated. However it is preferable for the

heat client to be closer to the source of the heat as heat is lost at a rate of 1 c per km. To

provide a basis for assessing the potential for CHP in Gloucestershire the locations of all

existing heat users within 1km of each of the 13 potential waste sites identified in the site

options consultation (2009) have been investigated and reported. This is because going

beyond 1km for existing properties would have led to an unmanageable number of sites

being identified. Identifying existing properties (housing, public buildings, industry etc) was

13

carried out using GIS6. The locations of 'potential' heat users within 2km of the each of the

sites was also investigated and recorded. This includes future developments that have not

yet been built but could come forward in the future such as sites that have been identified in

a Local Plan or Strategic Housing Land Availability Assessments (SHLAA) but have not yet

implemented. The site schedules for each of the thirteen site options are set out below.

4.6 There are currently investigations taking place as to the possibility of biogas produced

through the Anaerobic Digestion (AD) process being piped in to the national gas pipelines.

This is being supported by the National Grid. As such, the site schedules include

information on the distance of the site to a gas pipeline. The data was provided by Wales

and West Utilities and did not include pipelines owned by other gas transporters or private

owners. The information was given without obligation, or warranty, the accuracy thereof

cannot be guaranteed.

4.7 For each of the sites we have estimated the heat demand within the surrounding area.

The data used to estimate the heat demand was taken from an independent renewable

energy study produced by consultants ENTEC on behalf of Gloucestershire County Council

in June 20107. From this report it was calculated that the average heat demand for a typical

office/industrial unit was 92,682 kWh8 (derived using an average of the heat demand and

floor area of all of the office and industrial types set out in the ENTEC report). The average

heat demand (an average for flats and houses) for an average dwelling9 (with a floor area

of 80m²) was calculated to be 7,280 kWh.

4.8 It is important to note that these figures provide an indication of the potential only. It is a

desktop assessment based on an assumed average floorspace and heat demand. If a

developer wanted to create a district heating network it would be their responsibility to

establish accurate figures. It should also be noted that the estimated figures are for heat

demand only. We have not investigated the cost or infrastructure practicalities of

implementing a district heating network.

4.9 It should be noted that this desk top assessment does not take into account any of the

practical limitations outlined in Section 3, which would have to be considered fully prior to

implementation of a CHP/District Heating scheme.

The initial assessment work indicates that there would is significant potential demand for a

heat network within existing nearby development. However the heat network would have to

be retrofitted. There is also good potential for a heat network to be incorporated within any

future development due to the number of possible new dwellings associated with major

potential development nearby.
